A terminal is a fitting for electrical connection, by means of which a wire can be connected to an electrical device.

When the wire connecting part 100 is used, the wire connecting part 100 is fixedly arranged on an electrical device, and then the wire can extend into the wire connecting part 100 through the end part, so that the wire connecting part is screwed with the screw threads of the wire connecting part 100 through the screw 200, the wire is fixedly connected, and the circuit is conducted.

In the conventional terminal, the assembly of the wire connection part 100 and the screw 200 by screwing is required to be completed. The conventional method is to perform vibration feeding on the wire connection part 100 and the screw 200 through vibration plates, and then screwing. However, when the wire connecting portion 100 is subjected to vibration feeding, since the overall structure of the wire connecting portion 100 is a rectangular hexagon, particularly a square, the assembly surface is prone to inaccuracy during vibration feeding, and thus the wire connecting portion needs to be recovered into the vibration plate for re-feeding, or a manual correction mode is adopted, so that the efficiency of the whole assembly production process is reduced.

Detailed Description

The present application will be further described with reference to the specific embodiments, and it should be noted that, on the premise of no conflict, new embodiments may be formed by any combination of the embodiments or technical features described below.

In the description of the present application, it should be noted that, for the azimuth terms such as terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., the azimuth and positional relationships are based on the azimuth or positional relationships shown in the drawings, it is merely for convenience of describing the present application and simplifying the description, and it is not to be construed as limiting the specific protection scope of the present application that the device or element referred to must have a specific azimuth configuration and operation, as indicated or implied.

It should be noted that the terms "first," "second," and the like in the description and in the claims of the present application are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order.

Fig. 1 is a schematic structural view of a conventional connecting terminal. As shown in fig. 2, the connection part 100 of the connection terminal has six end surfaces in total, namely, a first end surface 110 for screw connection with the screw 200, a second end surface 120 opposite to the first end surface 110, and a third end surface 130, a fourth end surface 140, a fifth end surface 150 and a sixth end surface 160 adjacent to the first end surface 110.

It can be understood that, as shown in fig. 2, the wire connection portion 100 is formed by bending a rectangular strip, so that the sixth end face 160 and the second end face 120 of the wire connection portion 100 have the same structure, which is inconvenient for subsequent detection and identification.

As shown in fig. 3, in order to facilitate the subsequent detection and recognition, the strip may be first punched before the bending of the wire connecting portion 100, so as to ensure that the sixth end face 160 and the second end face 120 of the wire connecting portion 100 obtained after the bending have different structures.

It will be appreciated that the stamping location may be on the second end face 120 or the sixth end face 160, but that the stamping location is provided on the sixth end face 160 in view of the subsequent need for wire compaction by the second end face 120. The shape of the punch is various, and in order to facilitate the punching and reduce the cost, the through hole 161 may be punched in the sixth end surface 160. Meanwhile, in order to facilitate subsequent position recognition, the position of the through hole 161 cannot be located at the very center of the sixth end surface 160, preferably near one side of the first end surface 110, so that the orientation of the first end surface 110 can be recognized quickly.

The detecting device 9 is disposed at the detecting station 310, and when the feeding mechanism 5 conveys the wire connection portion 100 to be assembled through the detecting station 310, the detecting device 9 can detect an upward end face of the wire connection portion 100 to be assembled. The transposition mechanism 6 is disposed at the adjusting station 320, and the transposition mechanism 6 can perform transposition adjustment on the to-be-assembled wire connection portion 100 passing through the adjusting station 320 according to the detection result of the detection device 9, so that when the wire connection portion 100 is fed to the assembling station 330, the first end face 110 of the to-be-assembled wire connection portion 100 provided with the threaded hole faces upwards, so as to facilitate the subsequent assembling process. The assembling mechanism 8 is disposed at the assembling station 330, and the assembling mechanism 8 can assemble the screw 200 to be assembled fed by the feeding mechanism 7 with the wire connection portion 100 to be assembled fed by the feeding mechanism 5, thereby obtaining the required wire connection terminal.

In this embodiment, as shown in fig. 5 and 7, the mounting plate 301 is fixedly mounted on the side of the detection station 310 of the workbench 300, and the detection device 9 is fixedly mounted on the mounting plate 301, so that the detection device 9 is located directly above the detection station 310, and the detection end of the detection device 9 faces downward, so that the upward end faces of all the wire connection portions 100 to be assembled passing through the detection station 310 can be detected.

It will be appreciated that the detecting device 9 may detect the upward end face of the wire connection portion 100 in various manners, and there are conventional visual detection and acoustic wave detection, so the detecting device 9 may be an image capturing device or an acoustic wave generating device.

In one embodiment of the present application, as shown in fig. 5 to 11, the feeding mechanism 5 includes a vibration feeding tray 400, a first feeding portion, a second feeding portion, and a feeding member 51. The first feeding portion is transversely arranged, an extension plate 531 is arranged at the output end of the first feeding portion, and the feeding component 51 is mounted on the extension plate 531, so that the feeding component 51 can move transversely in a reciprocating mode under the driving of the first feeding portion, and the feeding component 51 reaches the tail end of the adjusting station 320 through the detecting station 310. The vibration feeding tray 400 is arranged at the side part of the workbench 300, a plurality of wiring parts 100 to be assembled are placed in the vibration feeding tray 400, so that the vibration feeding tray 400 can sequentially arrange the wiring parts 100 to be assembled onto the feeding component 51 through the feeding ports 410, the wiring parts 100 which are fed onto the feeding component 51 pass through the detection station 310 to the adjustment station 320 through the first feeding part, after the adjustment station 320 completes transposition adjustment through the transposition mechanism 6, the second feeding part can feed the wiring parts 100 which complete transposition adjustment to the assembly station 330 along the material guide plate 302 arranged on the workbench 300, and meanwhile, the second feeding part can also carry out blanking on the wiring terminals which are assembled by the assembly station 330, so that an automatic feeding process is realized.

It will be appreciated that, due to the long lateral distance from the inspection station 310 to the assembly station 330 on the table 300, the feeding accuracy may be reduced if only a single feeding portion is used for feeding. So this application divide into two parts with the pay-off process and go on, and one part carries out the pay-off through first pay-off portion, and another part carries out the pay-off through second pay-off portion to can effectually improve the pay-off precision, can also improve packaging efficiency simultaneously.

In this embodiment, as shown in fig. 5 to 7, the first feeding portion includes a first moving device 52 and a second moving device 53, the first moving device 52 is transversely and fixedly mounted on the workbench 300, the second moving device 53 is transversely and slidably mounted on the workbench 300, the second moving device 53 is connected to an output end of the first moving device 52, and the extension board 531 is disposed at an output end of the second moving device 53. The first moving device 52 drives the feeding member 51 to perform long-distance coarse movement by driving the second moving device 53, and the second moving device 53 is used for driving the feeding member 51 to perform short-distance fine movement.

It can be understood that when the feeding member 51 is located at the adjustment station 320 and performs transposition adjustment by the transposition mechanism 6, the transposition mechanism 6 has a high requirement on the position accuracy of the feeding member 51, so that during feeding of the feeding member 51, the first moving device 52 can drive the feeding member 51 to perform long-distance rapid coarse movement to a position close to the position to be transposed in the adjustment station 320, and then the first moving device 52 stops driving, and the second moving device 53 continues to drive the feeding member 51 to perform short-distance and slow fine movement until the feeding member 51 completely reaches the position to be transposed required in the adjustment station 320.

In this embodiment, as shown in fig. 5 to 7 and 11, the workbench 300 is further provided with a blanking station 340 at one lateral side of the assembly station 330. The workbench 300 is transversely provided with a guide plate 302 at the position of the assembly station 330, one end of the guide plate 302 is close to the tail end of the adjustment station 320, the other end of the guide plate 302 is close to the blanking station 340, the upper end face of the guide plate 302 is transversely provided with a guide groove 3020 penetrating through the assembly station 330, the width dimension of the guide groove 3020 is matched with the dimension of the wiring part 100, two ends of the guide groove 3020 are respectively communicated with the adjustment station 320 and the blanking station 340, and accordingly the transposition mechanism 6 can push the wiring part 100 after transposition to the end of the guide groove 3020. The second feeding part is arranged at the side part of the material guiding plate 302 and comprises a third moving device 54 and a fourth moving device 55, the third moving device 54 is transversely arranged at the side part of the material guiding plate 302 in parallel, the fourth moving device 55 is longitudinally arranged at the third moving device 54, and the output end of the fourth moving device 55 is connected with a feeding plate 551; the third moving device 54 can drive the fourth moving device 55 and the feeding plate 551 to move transversely and reciprocally parallel to the material guiding plate 302, the fourth moving device 55 can drive the feeding plate 551 to move longitudinally perpendicular to the material guiding plate 302, so that the feeding plate 551 can feed the wire connection part 100 positioned at the end part of the material guiding groove 3020 to the assembling station 330, and meanwhile, the feeding plate 551 can also feed the wire connection terminal assembled by the assembling station 330 to the blanking station 340.

Specifically, as shown in fig. 11, two ends of one side of the feeding plate 551, which is close to the feeding plate 302, are provided with feeding grooves 5510 which are matched with the wire connection part 100 in size, and the distance between the two feeding grooves 5510 is exactly equal to the distance from the end part of the feeding groove 3020 to the assembling station 330; while the depth of the guide channel 3020 on the guide plate 302 is smaller than the height of the wire connection part 100.

The specific working process of the second feeding part is as follows:

(1) The index mechanism 6 pushes the index completed wire portion 100 to the end of the guide chute 3020 near the end of the adjustment station 320.

(2) The third moving device 54 drives the fourth moving device 55 and the feeding plate 551 to move to one side of the feeding plate 302 close to the adjusting station 320, so as to ensure that two feeding grooves 5510 on the feeding plate 551 are exactly opposite to the wire connection portion 100 which is assembled on the assembling station 330 and the wire connection portion 100 to be assembled which is placed at the end of the guiding groove 3020.

(3) The fourth moving device 55 drives the feeding plate 551 to move longitudinally until the two feeding grooves 5510 are respectively clamped with the wire connection portion 100 which is assembled on the assembling station 330 and the wire connection portion 100 to be assembled which is placed at the end part of the guide groove 3020.

(4) The third moving device 54 drives the fourth moving device 55 and the feeding plate 551 to move to a side of the material guiding plate 302 close to the blanking station 340, so that the feeding plate 551 feeds the wire connection portion 100 to be assembled to the assembling station 330, and simultaneously blanking the wire connection terminal assembled on the assembling station 330 to the blanking station 340.

(5) The feeding plate 551 is kept stationary, so that the feeding plate 551 limits the wire connection portion 100 to be assembled at the assembling station 330 through the feeding groove 5510, thereby facilitating the assembling mechanism 8 to assemble the screw 200 with the limited wire connection portion 100.

(6) The fourth moving device 55 drives the feeding plate 551 to longitudinally reset and move until the feeding groove 5510 is separated from the wire connection part 100 which is assembled. And then the automatic cycle assembly process of the wiring terminal can be completed by cycling the above processes.

When the vibration loading tray 400 loads the wire connection portion 100 to be assembled onto the feeding member 51, the wire connection portion 100 faces the upper end face as shown in fig. 4.

I.e., six end faces of the wire connection portion 100 may all face upward, and each end face has four different orientations. When the wire connection portion 100 is assembled with the screw 200, the first end face 110 of the wire connection portion 100 with the threaded hole is only required to face upwards, and the specific orientation of the first end face 110 when facing upwards is not required to be considered.

Thus, when the wire connecting portion 100 is fed to the feeding member 51, the following three cases exist in the upward end face thereof:

(1) When the first end face 110 is directed upward, no indexing adjustment of the wire connection 100 is required when passing through the adjustment station 320.

(2) The second end 120 opposite to the first end 110 faces upward, so that when the wire connection part 100 passes through the adjusting station 320, the first end 110 can be turned upward by only turning the wire connection part 100 by 180 degrees, and the deflection angle of the wire connection part 100 is not required or is arbitrarily adjusted.

(3) Any one of the third end surface 130, the fourth end surface 140, the fifth end surface 150 and the sixth end surface 160 adjacent to the first end surface 110 faces upward, and when the wire connection part 100 passes through the adjusting station, the wire connection part 100 needs to be turned by 90 degrees, and meanwhile, needs to be horizontally deflected, and the specific deflection angle is influenced by the orientation of the upward end surface.

To satisfy the above-described index adjustment of the wire connection portion 100, one embodiment of the present application, as shown in fig. 12 to 18, includes a rail plate 61, a plurality of pairs of flipping assemblies 62, and a liftout device 63. The guide rail plate 61 is transversely arranged at the adjusting station 320, and a chute 610 is arranged on the guide rail plate 61. The extension board 531 may drive the feeding component 51 to slide along the chute 610 under the driving of the first feeding portion, so that the feeding component 51 drives the wire connecting portion 100 to be assembled to deflect through a rotating structure between the feeding component and the chute 610. The two turnover assemblies 62 of each pair are symmetrically arranged at two sides of the extending direction of the guide rail plate 61, so that the turnover assemblies 62 of each pair are matched with each other to turn over the wire connection part 100 to be assembled in the feeding part 51; and one pair of turnover assemblies 62 can drive the wire connection part 100 to be assembled on the feeding part 51 to turn 180 degrees, and the other pairs of turnover assemblies 62 can drive the wire connection part 100 to be assembled on the feeding part 51 to turn 90 degrees. The ejector 63 is disposed at the end of the guide rail 61, and the ejector 63 can eject the wire connection part 100 after the transposition from the feeding member 51 to the guide groove 3020 on the guide rail 302.

In this embodiment, as shown in fig. 7, 11 and 12, the guide plate 302 and the guide rail plate 61 are arranged in a laterally offset manner, and an opening facing the guide rail plate 61 is formed at one end of the guide rail 3020 near the guide rail plate 61, and the opening is opposite to the ejector 63, so that the ejector 63 can eject the wire connection portion 100 out of the feeding member 51 and enter the guide rail 3020 along the opening.

In the present embodiment, as shown in fig. 8 to 10, in order to facilitate the operation of the index mechanism 6 on the wire connection portion 100 placed on the feeding member 51, a preferable structure of the feeding member 51 is provided. The feeding member 51 comprises a U-shaped feeding frame 511 and a supporting portion 513, a spherical feeding cavity 5110 is arranged in the feeding frame 511, and the wire connecting portion 100 to be assembled can be placed in the feeding cavity 5110 in an inscribed manner; the feed chamber 5110 communicates with all three sidewalls of the feed frame 511. The lower extreme of pay-off frame 511 is provided with adapter sleeve 5111, is provided with the mounting groove 5310 that is slightly greater than pay-off frame 511 rotation size on the extension board 531 simultaneously, and pay-off frame 511 passes through adapter sleeve 5111 rotation to be installed in mounting groove 5310. The end of the connecting sleeve 5111 extending out of the lower end surface of the extension plate 531 is provided with a gear 512, and the supporting part 513 is slidably installed at the bottom of the feeding cavity 5110.

It can be appreciated that the detection station 310 is disposed at one end of the guide rail plate 61 near the first feeding portion, and the vibration feeding tray 400 performs feeding at the detection station 310. Therefore, when the feeding member 51 is receiving, the opening of the feeding frame 511 is facing the feeding opening 410 of the vibration feeding tray 400, so that the vibration feeding tray 400 can feed the wire connecting portion 100 to be assembled into the feeding cavity 5110, at this time, the upper end face of the supporting portion 513 is flush with the bottom end of the feeding opening 410, and when the wire connecting portion 100 is fed into the feeding cavity 5110, the lower end face of the wire connecting portion 100 can abut against the upper end face of the supporting portion 513, so as to ensure that the wire connecting portion 100 in the feeding cavity 5110 is stable through the supporting portion 513 in the feeding process of the feeding member 51.

Meanwhile, in the sliding process of the feeding frame 511 along the sliding chute 610, multiple deflection can be performed, and the angle of each deflection is an integral multiple of 90 degrees, so that when the feeding frame 511 moves to a to-be-turned area of any pair of turning assemblies 62, the feeding frame 511 is provided with two opposite side end faces respectively opposite to the two turning assemblies 62 in the position area, and the turning assemblies 62 can conveniently penetrate through the feeding frame 511 to turn the wiring part 100 in the feeding cavity 5110.

In the present embodiment, the structure of the supporting portion 513 is various, including but not limited to the following two:

structure one: the supporting portion 513 includes a straight rod section 5131 and a supporting table 5132, the straight rod section 5131 is fixedly connected in the connecting sleeve 5111, and the upper end of the straight rod section 5131 is elastically connected to the lower end of the supporting table 5132 through an elastic member. In a natural state, the upper end surface of the support table 5132 is flush with the bottom end of the feeding port 410, so that when the wire connection portion 100 is fed into the feeding cavity 5110, the upper end surface of the support table 5132 abuts against the lower end surface of the wire connection portion 100. When the overturning assembly 62 overturns the wire connecting portion 100, the wire connecting portion 100 can elastically press the supporting table 5132 downwards, so that the wire connecting portion 100 can be overturned smoothly.

And (2) a structure II: as shown in fig. 9, 13 and 18, a sliding hole for communicating the feeding cavity 5110 with the outside is provided in the connection sleeve 5111; the supporting portion 513 includes a supporting table 5132 and a straight rod segment 5131 which are fixedly connected, and the supporting portion 513 is slidably mounted in the sliding hole through the straight rod segment 5131. Thus, when the feeding member 51 slides along the chute 610 or performs feeding, the straight rod section 5131 abuts against the bottom of the chute 610 through the lower end to ensure that the upper end face of the support table 5132 is flush with the lower end face of the feeding opening 410. Meanwhile, a plurality of grooves 6102 are formed on the bottom end surface of the sliding groove 610 on the guide rail plate 61, the specific number of the grooves 6102 is the same as the number of pairs of the flipping components 62, and each groove 6102 is correspondingly located in the region to be flipped of each flipping component 62. When the feeding member 51 moves into the region to be turned, the straight bar section 5131 moves the support table 5132 downward to be spaced from the bottom end of the wire connection part 100 by the engagement with the groove 6102, so as to ensure that the wire connection part 100 has a sufficient spacing region for turning.

In this embodiment, as shown in fig. 13 and 18, one side of the chute 610 is provided with a plurality of spaced rack segments, and the feeding frame 511 is engaged with the rack segments through the gear 512 to form a rotating structure. The rack segments are offset from the corresponding areas to be flipped for each pair of flipping assemblies 62 so that the horizontal deflection adjustment is completed before the feeding member 51 delivers the wire section 100 to be assembled to the desired area to be flipped.

It will be appreciated that there are a variety of ways of adjusting the indexing of the wire connection 100, one preferred way of adjusting is: the flipping assembly 62 can only flip the wire section 100 in one direction; meanwhile, the rotating structure can only drive the wire connection part 100 to perform unidirectional deflection.

Thus, for the case where any one of the third end face 130, the fourth end face 140, the fifth end face 150, and the sixth end face 160 adjacent to the first end face 110 faces upward, the wire connection portion 100 may need to be subjected to four angular deflection cases of 0 °, 90 °, 180 °, and 270 °.

In this embodiment, as shown in fig. 12, 13 and 17, the above-described manner of adjusting the transposition of the wiring portion 100 is satisfied. The multi-section rack section comprises at least three first rack sections 6101 and one second rack section 6103 which are arranged at intervals; the engagement length of each first rack segment 6101 and the gear 512 is one quarter of the circumference of the gear 512, that is, when the gear 512 engages with the first rack segment 6101 of each segment, the feeding frame 511 drives the connection portion 100 to rotate by 90 °. The second rack segment 6103 is disposed at the end of the chute 610, and the engagement length of the second rack segment 6103 corresponding to the gear 512 depends on the position of the guide plate 302. If the guide plate 302 approaches the feeding side of the vibratory feeding tray 400 relative to the guide plate 61, the meshing length of the second rack segment 6103 corresponding to the gear 512 is one fourth of the circumference, i.e. the feeding frame 511 is exactly horizontally deflected by 360 ° after passing through the second rack segment 6103, so as to ensure that the opening of the feeding frame is opposite to the guide groove 3020 on the guide plate 302; if the guide plate 302 is far away from the feeding side of the vibratory feeding tray 400 relative to the guide plate 61, the meshing length of the second rack segment 6103 corresponding to the gear 512 is three-quarters of the circumference, so as to ensure that the opening of the feeding frame 511 can be opposite to the guide groove 3020 on the guide plate 302 after passing through the second rack segment 6103; and the ejection device 63 can conveniently eject the wiring part 100 which is subjected to transposition adjustment in the feeding frame 511 to the feeding cavity 5110 through the expansion and contraction of the output end to the guide chute 3020.

Meanwhile, the turnover assemblies 62 have five pairs, the turnover assemblies 62 of each pair are arranged at intervals, and each pair of turnover assemblies 62 can turn over the wiring part 100 in the region to be turned over, which is correspondingly arranged on the chute 610.

In one embodiment of the present application, as shown in fig. 12, 14-18, the flip assembly 62 includes a first rotating device 621, a guide sleeve 622, and a plunger 623. The first rotating device 621 is fixedly installed on the table 300; the guide sleeve 622 is fixedly arranged on a fixed seat 601 arranged on the workbench 300, and a traction groove is formed in the inner wall of the guide sleeve 622; the pressing rod 623 passes through the guide sleeve 622 to be in spline connection with the output end of the first rotating device 621, and meanwhile, the pressing rod 623 is matched with the traction groove through a guide block 6230 arranged on the side wall. When the wire connection part 100 to be assembled in the feeding frame 511 needs to be turned, the first rotating device 621 can rotate to drive the pressing rod 623 to rotate, and the pressing rod 623 can approach and clamp the wire connection part 100 to turn to a required angle through the cooperation of the guide block 6230 and the traction groove in the rotating process.

In this embodiment, as shown in fig. 15 and 16, the traction groove includes two symmetrically arranged chute sections 6221, and both ends of the two chute sections 6221 are respectively communicated through a first communication section 6222 and a second communication section 6223 in the circumferential direction; wherein the first communication section 6222 is adjacent to the guide rail plate 61, and a central angle corresponding to an axial projection line of the first communication section 6222 along the guide sleeve 622 is α.

It will be appreciated from the foregoing that the flipping assembly 62 is required to drive the wire portion 100 to flip 90 ° or 180 °; and when 90 ° overturning is performed, the wire connection portion 100 may need to perform four angular deflection conditions of 0 °, 90 °, 180 ° and 270 °, so that among the five pairs of overturning assemblies 62, the circumferential angle α corresponding to the first communication section 6222 in the guide sleeve 622 on one pair of overturning assemblies 62 is 180 °, and the central angle α corresponding to the first communication section 6222 in the guide sleeve 622 on the other four pairs of overturning assemblies 62 is 90 °.

The operation of the flipping assembly 62:

initially, the end of the lever 623 is away from the rail plate 61 and at this time the guide block 6230 on the lever 623 is located within the second communication segment 6223.

When the feeding part 51 conveys the wiring part 100 which needs to be subjected to transposition adjustment to a corresponding area to be overturned along the chute; the first rotating device 621 is started to drive the pressing rod 623 to rotate unidirectionally, and during the rotation of the pressing rod 623, the guide block 6230 can slide along the second communicating section 6223 to the end of one of the chute sections 6221 and continue to slide along the chute section 6221 towards the first communicating section 6222. In this process, the pressing rod 623 also moves in the axial direction of the guide sleeve 622 while rotating until the end of the pressing rod 623 makes pressing contact with the end face of the wire connecting portion 100 facing the region to be turned. The two pressing bars 623 of each pair may be clamped by pressing opposite side end surfaces of the wire connection part 100.

Subsequently, the presser bar 623 continues the unidirectional rotation of the guide block 6230 along the first communication segment 6222. Because of the circumferential arrangement of the first communication section 6222, the pressure lever 623 only performs a circumferential rotation without an axial movement during this process, so that the clamped connection portion 100 can be turned over by an angle corresponding to the central angle α of the first communication section 6222.

Finally, the presser bar 623 continues to rotate unidirectionally, so that the guide block 6230 slides along the other chute section 6221 towards the second communication section 6223. In this process, the pressing lever 623 may also move in the axial direction of the guide sleeve 622 while rotating to be away from the feeding frame 511 on the guide rail plate 61, thereby releasing the clamping of the wire connection part 100 to facilitate the subsequent re-conveyance of the wire connection part 100.

It will be appreciated that in order to avoid rigid contact between the presser bar 623 and the wire connection portion 100, the end portion of the presser bar 623 may be made of an elastic material.

For ease of understanding, the working process of the indexing mechanism 6 may be briefly described as follows:

for convenience of description, the mounting positions of the flipping assemblies 62 may be specifically set, for example, four pairs of flipping assemblies 62 for 90 ° flipping are arranged at intervals on one side of the guide rail plate 61 near the first feeding portion, and the required horizontal deflection angles corresponding to each pair of flipping assemblies 62 arranged in sequence are 0 °, 90 °, 180 ° and 270 ° in sequence. And a pair of flipping units 62 for 180 degree flipping are disposed at a distance from one side of the rail plate 61 near the second feeding portion.

(1) The detecting device 9 can detect the upward end face of the wire connection part 100 fed into the feeding chamber 5110.

(2) If the upward end surface of the wire connection portion 100 placed in the feeding cavity 5110 is just the first end surface 110, the overturning assembly 62 is not started, so that the first feeding portion drives the feeding frame 511 and the placed wire connection portion 100 through the extension plate 531, when the first feeding portion slides to the right front of the material ejection device 63 along the chute 610, the opening of the feeding frame 511 is opposite to the opening of the material guide groove 3020 on the material guide plate 302 after the feeding frame 511 is deflected by a certain angle, and the output end of the material ejection device 63 can penetrate through the feeding frame 511 to push the wire connection portion 100 in the feeding cavity 5110 into the material guide groove 3020.

(3) If the upward end surface of the wire connection portion 100 disposed in the feeding cavity 5110 is the second end surface 120, the first feeding portion drives the feeding frame 511 and the disposed wire connection portion 100 through the extension plate 531, and slides along the chute 610 to the region corresponding to the to-be-turned region of the last pair of turning assemblies 62. The pair of flip elements 62 is thereby actuated to flip the wire section 100 unidirectionally 180 ° by the presser bar 623 to ensure that the flipped first end face 110 of the wire section 100 faces upward. The first feeding section then continues to convey the feeding member 51 to the position of the ejector 63 to effect the wire section 100 to be pushed to the guide plate 302.

(4) If the upward end face of the wire connection part 100 placed in the feeding cavity 5110 is any one of the third end face 130, the fourth end face 140, the fifth end face 150 and the sixth end face 160 adjacent to the first end face 110, the detecting device 9 can continuously determine the position of the first end face 110 at the moment; i.e., the first end face 110 is oriented at an angle β relative to the direction of flip of the flip assembly 62. When β is 0 °, the first feeding portion drives the feeding frame 511 and the placed wire connection portion 100 to slide along the chute 610 to the region to be turned corresponding to the first pair of turning assemblies 62; when β is 90 °, the first feeding portion drives the feeding frame 511 and the placed connection portion 100, and slides along the chute 610 to the region to be turned corresponding to the second pair of turning assemblies 62, in this process, the feeding frame 511 is engaged with a section of the first rack segment 6101 to drive the connection portion 100 to deflect 90 ° horizontally, so that the value of the included angle β is 0 °; when β is 90 °, the first feeding portion drives the feeding frame 511 and the placed connection portion 100, and slides along the chute 610 to the region to be turned corresponding to the third pair of turning assemblies 62, in this process, the feeding frame 511 and the two first rack segments 6101 are engaged to drive the connection portion 100 to deflect 180 ° horizontally, so that the value of the included angle β is 0 °; when β is 270 °, the first feeding portion drives the feeding frame 511 and the placed wire connection portion 100, and slides along the chute 610 to the region to be turned corresponding to the fourth pair of turning assemblies 62, and in this process, the feeding frame 511 and the three first rack segments 6101 are engaged to drive the wire connection portion 100 to deflect horizontally 270 °, so that the value of the included angle β is 0 °. When the feeding frame 511 drives the wire connecting portion 100 to deflect and then locate in the corresponding region to be turned over, the corresponding turning component 62 is started to drive the wire connecting portion 100 to turn over by 90 ° unidirectionally through the pressing rod 623, so as to ensure that the first end face 110 of the turned wire connecting portion 100 faces upwards. The first feeding section then continues to convey the feeding member 51 to the position of the ejector 63 to effect the wire section 100 to be pushed to the guide plate 302.

It will be appreciated that, as shown in fig. 20, one end of the limit groove 741 is provided with an opening, which is opposite to the loading opening 410 of the vibration loading tray 400. Initially, the loading plate 73 is right opposite to the loading opening 410 through the loading groove 731, and the depth of the loading groove 731 is equal to the height of the threaded section on the screw 200, so that when the vibration loading disc 400 loads the screw 200 into the loading groove 731 along the loading opening 410, the upper part of the screw 200 is located in the limit groove 741.

As shown in fig. 21, the fifth moving device 72 drives the feeding plate 73 to move towards the feeding hole 710, and in the process of transversely moving the feeding plate 73 towards the feeding hole 710, the feeding plate 73 further moves longitudinally through the cooperation of the pin 732 and the guide groove 742 until the feeding plate 73 moves to be level with the feeding hole 710, and at this time, the feeding groove 731 is just out of cooperation with the screw 200; meanwhile, in the process, the screw 200 is kept to move transversely until being located right above the feeding hole 710 through being matched with the limit groove 741, and is discharged into the assembly mechanism 8 along the feeding pipe 75 under the action of gravity after being out of being matched with the feeding groove 731 so as to facilitate the subsequent assembly of the wiring terminal.

In one embodiment of the present application, as shown in fig. 22 to 24, the assembly mechanism 8 includes a support base 81, a sixth moving device 82, a seventh moving device, a second rotating device 83, and a discharging member 84.

The feeding mechanism 7 can feed the screw 200 to be assembled into the discharging part 84. The seventh movement means may move the blanking member 84 vertically to be close to or away from the assembly station 330. When the discharging component 84 is close to the assembling station 330, the sixth moving device 82 can drive the second rotating device 83 to vertically move, so that the output end of the second rotating device 83 is matched with the screw 200 in the discharging component 84 through the screwing component 831, and further the screwing component 831 can drive the screw 200 to be screwed with the wire connection portion 100 located in the assembling station 330 under the rotation driving of the second rotating device 83, so that the assembling of the connecting terminal is completed.

In this embodiment, as shown in fig. 23 and 24, the discharge member 84 includes a discharge frame 841, a pair of sliders 842, and a pair of springs 843. The discharging frame 841 is fixed on the supporting seat 81, a sliding cavity 8411 is arranged in the discharging frame 841, sliding blocks 842 are symmetrically and slidably arranged in the sliding cavity 8411, the sliding blocks 842 are elastically connected with the discharging frame 841 through springs 843, and a discharging cavity 8420 for placing screws 200 is formed between the two sliding blocks 842 in a matching mode; one side of the discharge frame 841 is provided with a discharge hole 8410 communicated with the discharge cavity 8420, and the feeding mechanism 7 can be communicated with the discharge hole 8410 through the lower end of the feeding pipe 75, so that the feeding mechanism 7 can feed the screw 200 into the discharge cavity 8420 along the discharge hole 8410. The screwing part 831 can vertically extend into the discharging cavity 8420 to be matched with the screw 200 to be assembled, and when the screwing part 831 moves down to screw the screw 200, the screwing part 831 can drive the sliding block 842 to move horizontally, so that the size of the discharging cavity 8420 can be enlarged to be larger than that of the screw 200, and the discharging part 84 moves up to the discharging cavity 8420 to be separated from the assembled screw 200 under the drive of the seventh moving device, so that the subsequent discharging process is facilitated.

In this embodiment, as shown in fig. 23 and 24, the lower end of the screwing part 831 can be engaged with the cross groove at the top of the screw 200. The diameter of the upper section of the screwing part 831 is larger than that of the lower section, and meanwhile, a tapered extrusion groove 8421 is formed above the discharging cavity 8420 by the sliding block 842. Therefore, in the process of screwing the screwing part 831 downwards, the screwing part 831 can be continuously matched with the extrusion groove 8421 through the upper section, and the two sliding blocks 842 can move downwards along with the continuous screwing part 831 to horizontally move away from each other and stretch the spring 843, so that the size of the discharging cavity 8420 is ensured to be gradually enlarged to be larger than the maximum diameter size of the screw 200.
